A pressure swing adsorption process for the separation of nitrogen from a mixture of the same with methane, utilizing two separate PSA stages, one containing a nitrogen selective crystalline zeolite, and the second containing a methane selective adsorbent.
Cette invention a trait à un processus d'adsorption modulée en pression permettant l'extraction d'azote d'un mélange constitué par cet azote et par du méthane. Ce processus fait intervenir deux phases distinctes d'adsorption modulée en pression, l'une contenant de la zéolithe cristalline sélective de l'azote et la seconde un adsorbant sélectif du méthane.
